optional OS1562-MB mounting
bracket, $95, shown smaller
than actual size.
The OS1561 and OS1571 standalone line of sight infrared
pyrometers provide a 10 msec time
constant for applications requiring
exceptionally fast and accurate noncontact temperature measurements.
It is a compact and rugged unit,
with 1 mv/degree outputs, and is
compatible with a variety of
temperature instrumentation
including meters, recorders and
dataloggers. It has an optional
linear output of either 0 to 10 Vdc
or 4 to 20 mA
The detector has a built-in
synchronous demodulation
circuitry, making it ideal for use
in applications with high levels of
electrical noise.
The OS1571 offers signal
processing outputs of peak sense
and hold. The pyrometer also has
the ability for backlighting which
defines the exact area being
measured by projecting an image
of light at a particular point on
the object.
The OS1561 and OS1571 detectors
are available in various temperature
ranges with specific spot sizes at
specific target distances (see
ordering matrix on next page for
details). It is intended for fixed
mount applications where the
pyrometer location, relative to
the object being measured, will
be constant.

Model OS1561 can use range codes R1 thru R4. Model OS1571 can use range codes R1 thru R8.
Ordering Example: OS1571F-R6-MA, fixed distance pyrometer with 1112 to 4352°F range, 1 mV/°F
output, optional 4 to 20 mA second output and signal averaging, $3915 + 1000 + 125 = $5040.
